IMPROVEMENT IN PUMPS.

The Schedule referred to in these Letters Patent: and making part of 'the same.

'l'o all whom 'it may conce-rn:

Beit known that I, EDWARD T. JENKINS, of Brook- -lyn Kings county, New4 York, have invented, made,

and applied to use a new and improved Pneumatic Pump, for pumping wines, liquors, and other fluids ont ot' barrels, (tasks, or other vessels; and that the following -is a full, clear, and correct description ofthe same, reference being had to the accompanying drawingsmaking a part of this specification, and to thc letters of reference marked thereon, in which- Figure l is a side elevation of my v,improved pnen- A matic pump applied to a barrel.

Figure 2, a vertical cutseetion of the pump.' Figure 3, a view showing the construction of the upper valve.

In the drawings like parts of the invention are des.

ignated by the same letters ofrefereuce The nature of the present invention consists in certain improvements, as more fully'liereiuafter set forth, in the construction cfa pneumatic pump, the object of the invention vbein-g to furnish a simple and e'ective pump for kthe purposes already indicated. 'v

To enable those skilled in the arts to make and use my invention, I will describe the construction and op"- eration ofthe same.

A shows the chamber of my improved pump, in

-u'hich is contained the piston or upper valve B. lThis chamber may be formed of brass or anysuitable metal, and the piston is also formed of brass, the space between the same endet-he chamberV being packed, as is usual. This pistonis provided upon its under side witha valve (see iig) formed of astrip'of leather,

4 mbbcr, or any suitable material. This valve is thev upper valve of the piimp.

C shows a connecting-rod, connecting the piston to a lever, '1), by whiclrtliesame is operated, one end of said lever being pinned iii-the flanges, a upon the discharge-pipe H.

Within the chamber-A, a short distance below the piston, is secured the lower valve E, formed similarly 'to the upper valve. o

The lower-portion of the chamber Ais made tapering,and is threaded, so that the pump may be readily and securely fastened into the barrel, Cask, or other vessel from which the uid is to be forced or withdrawn; and to aid in inserting or withdrawing the same the chamber isi-provided with a handle, F, by which thepump may be readily turned.

G show's the barrel, cask,or ,other vessel-to be emptied, into which the pump is inserted by screwing the threaded portion ofthe chamber into the bung-hole of the barrel or casl'c, or into au opening made in the,

vessel..A

H shows the l discharge-pipe, through which the liquid or liuid is forced out of the barrel, cask, or other and asmaller and shorter one, designated as H2, which smaller pipe is inserted within the larger one, and is adjustable to the extent of its length, being held within the same by means ota nut or collar, h, passedl over the threaded end of the' pipe H.

The object obtained by making the pipe telescopic is, that the pipe is always brought to bear upon the bottom ofthejbarrel, cask, or other vesselby extending or withdraw'ingfthe shorter pipe H2, thus adapting the pump to barrels, casks or other vessels of different sizes.4 The end of' the pipe H2 is cap-shaped, and is provided with a series of small perforations extending into this pipe, through which the fluid enters and passes to the main pipe H,

- The pipe H is provided with a dischargeoriice, as at J, aDd-alSoWith a rim, J2, supported upon a spindle,

K, by which the discharge of the fluid may be regulated or governed at the pleasure `of the operator.

- Such being the construction, the operation isas follows:

The pump is inserted in the barrel, cask or other vessel, the contents of which are to be forced out, by removingkthe bung from theibarrel or cask, or'by makf ing an opening in the vessel suiicientlylarge to allowv the tapering threaded portion of the chamber to he secured in the same, and is secured in the same so `formed of the strip of leather, rubber, or suitable material, which valve-is' .opened-as the valve-seat is depressed, and closed as the same iselevated through the movement ofthe lever D, .and passes through the lower valve (operating in the same manner as the upper valve) into the barrel,l cask, or other vessel upon the surface of; the contents of the same.

The movement ofthe lever is continued unt-il a sufficient quantity o f air has been forced down into the barrel, cask, or other vessel to force the coutentsof the same through the perforations'in the lower or "shorter tube up and into the. larger ormain pipe,

where, as the movement of the lever is continued, it rises until `it reachesthc discharge-orifice.

When the conteutsofthe barrel, cask, or othervessel reachthis point, the valve J 2, supported upon the spindle K, VmaybeL `opened by turning the wheel L upon one end of the spindle, and the contents of the barrel, cask, or othervessel will be discharged through the discharge-orifice, the motion of thelever operating,r the upper valve being continued.

lt will be observed that in the operation ot' my improved pump I makeuse of the same opening in the vessel to be emptied to allow the air to cuter therein that the discharge-pipejis placed in; also, that the liquor or liquid discharged does not pass through any portion of the pump that it may be necessary topaclr, and that by the employment of the valve J 2 complete control ofthe discharging or trausferring'of the liquid or fluid is obtained; thus any desired quantity can be drawn of and the discharge then be stopped b y closing the valve J2.

In the case .of high-priced wines, the features, that no contact takes place between the liquor and the` pump, save the telescopic pipe through which it passes, and that the discharge ofthe liquor can be controlled, are'of value, particularly the latter feature, if the liquor is to` be rbottled,7 as,` by the ability'to control the discharge, no liquor need be wasted'orlost, while the non-contactof itwith any portion of the apparatus,

save the telescopic pipe, preserves in a great degree.

usually employed, one to pump'and a second one to ll'.:

For the purposes of bott-ling liquors, wines, or fluids, my apparatus will be found particularly valuable,.wl1ile it may be generally used for raising iluids and trans ferring them from one vessel lto another. The apparatus can be readily adapted to the desired object, is easily managed, and will be found 'economical in its working.

Having thus set forth my invention,

What I claim as new ,is-

1. A pueumatic'pum'p, applicable to Vthe'discharge of'liquids from close vessels, having'a chamber, which serves as the cylinder of the condensing-pump, while affording a passage to the discharge-pipe through which the liquids escape from the vessel, said parts 'being constructed and arranged as described and shown.

2. The combination, with the'charnber A,ot" the valves AB and E, connection Crlever I), andtelescopie discharge-pipe H, when the same shall bc-c'onstructedf and operate substantially as and foi-the purpose set forth.

3. 1n combination with the second clause of claim,

the valve J 2 and spindle K, substantially as and for the pnl-noses set forth.
